Micropower Precision
Series Reference Family
Description
The LT®1460 is a micropower bandgap reference that
combines very high accuracy and low drift with low power
dissipation and small package size. This series reference
uses curvature compensation to obtain low temperature
coefficient and trimmed precision thin-film resistors to
achieve high output accuracy. The reference will supply
up to 20mA with excellent line regulation characteristics,
making it ideal for precision regulator applications.
This series reference provides supply current and power
dissipation advantages over shunt references that must idle
the entire load current to operate. Additionally, the LT1460
does not require an output compensation capacitor, yet
is stable with capacitive loads. This feature is important
where PC board space is a premium or fast settling is
demanded. In the event of a reverse battery connection,
these references will not conduct current, and are therefore
protected from damage.
The LT1460 is available in the 8-lead MSOP, SO, PDIP and
the 3-lead TO-92 and SOT23 packages.
